Chapter 7037 - PETROLEUM CONTAMINATED SOIL MANAGEMENT
Part 7037.2300 - SPREADING AND INCORPORATION OF PETROLEUM CONTAMINATED SOIL

Petroleum contaminated soil must be spread uniformly. Petroleum contaminated soil must be incorporated into the upper four to six inches of native soil as soon as feasible but no longer than 48 hours after spreading. In order to minimize soil moisture loss and volatile loss of the petroleum contaminants, initial incorporation must be conducted only to the degree that most soil clods are broken up and petroleum contaminated soil and native soil mixing occurs. For most land treatment applications, one or two passes with a tillage implement will result in adequate incorporation during a single tillage cycle.
